GYTA53 24-Core Double-Armored Direct Buried Outdoor Single-Mode Fiber Optic Cable
GYTA53 is a double-armored outdoor single-mode fiber optic cable designed for conduit-free direct burial. Built with ITU-T G.652D fibers, jelly-filled loose tubes, a central steel wire, APL aluminum tape, PSP corrugated steel tape armor, and a heavy-duty PE sheath, it offers high crush resistance, 100% moisture blocking, and termite protection. Ideal for long-haul telecom backbones, MAN, and rugged underground campus networks.

Overview
The GYTA53 double-armored direct-buried optical fiber cable delivers high-performance transmission for long-haul telecom backbones and campus networks. Engineered for conduit-free underground installation, GYTA53 withstands heavy soil pressure, moisture, and biological threats. Key Features & Structure: - Fiber & Loose Tube: Color-coded G.652D single-mode fibers in jelly-filled loose tubes for moisture resistance. - Strength Member: Central steel wire ensures high tensile load capacity. - Double Armor Protection: APL aluminum tape + inner PE sheath + PSP corrugated steel tape + outer PE sheath provide maximum crush resistance and termite defense. - Direct Burial: Performs reliably in tropical, wet, or harsh soil without additional conduit. Applications & Compliance: Suitable for MAN, inter-building links, and ISP distribution networks. Fully compliant with IEC 60794 and ITU-T G.652D standards.
Key Features
Direct-buried, no conduit needed
Double-armor construction qualifies for direct burial in any soil environment, including tropical high-water-table and termite-active conditions.
G.652D fiber
Low water-peak single-mode fiber — supports all CWDM channels and 100G/400G optics over installed campus distances.
Applications
Campus and outside plant
Inter-building trunks across campuses, direct-burial site fiber, aerial spans over distribution poles.
Telecom access network
FTTH and FTTB last-mile fiber distribution.
